4 Claims.

1; v invention relates to :a new. metal storm window and more particularly to a window with extruded stiles and a channel in"the.:outer.sur-. face of each :stile containing an :extenderwhich is preferably pressedbya spring against the wall of the opening into which the window fits.-

The elementsforming the frame and'the top, bottom,'and middle rails of the sashes are of uniform dimensions throughout'their length except where portions may "becut away. They are preferably formed by the extrusion of a metal. or plastic. A li ht-weightaluminum alloy is the preferred construction material. These elements may boom; to length from the extruded strips either at the plant where the: extruded strips are formed .or at scattered assembly plants. Any unoutstrip of any of this 'stock-maysbeusedforany sized window. The frame win preferably be assembled with the'stilesan inch .or-two lo er than required. At thehouseor other place-e1"- installa tion these stiles arerreadilycut-to length; the -win-: dow is put in place-with the top of the window flush with the topof the casing or other opening to which the window-is to be fitted. The-ex tenders are then adjusted E170- fillsin :the opening. The stiles may bepmade of .two extruded-parts. The-top. and bottom portions QfieaCh.-1Sliile are of different cross section. Theymay bea eparately formed, .eachof: the desired cross: section. and then joined-as: by welding. As an. alternative method, a single piece :of uniform cross section from the top :to the bottom, the 'lengthofthe stile, may lee-employed; :and .a.;separate element of 'uniform cross section may be united toits bottom portion-to convert this to the; desired cross-sectional configuration. Whatever. the method-of -.c.onstruction, there isaachannel in the bottom :halfof .each stile-in which the lower sash Slides. This is locatedjrtowardzthe inside faceof the frame. The inner wall of the channel is out awayitowardits top "to facilitate the insertion and removal of the lowersash. On' the upper portion of that wall of .each tile. which'faces the sashestoward the outside :face of. theirame. there is a vertical ledge or rest which extends substantially the whole: of :the :upperhaltof the stile. It prevents the upper: sash from falling I out and forms a weather seal with theonter face Fig. 3 is. anwenlarged s ction on the line '.3 ;3 ofF g; .1;

In alternative arrangements explained in connection with Figs. 6-9, the extenders in the stiles may be held in place by springs.

Fig. 3 is a section of the lower portion of the stile 3. The back member 30 is equal in length and width to the member 20 of the upper portion of the stile. The channel formed by the parts (H, 32, and a portion of the part 33 (which is equal in length to the part 30 is equal in depth to the inner portion of the element 20 so that the part 32 coincides exactly with the part 2|. The front wall 33 of the lower element of the stile coincides exactly with the front wall 22 of the upper element of the stile. The wing I6 is thus formed by the parts 30, 34, and 3|. It is the upper edge of this wing which forms the rest I (Fig. 5) for the bottom of the upper sash.

The extender shown in Fig. 3 is the same extender a shown in Fig. 6. The parts of the upper and lower portions of the stile coincide to form a channel on the lateral face of the frame, which extends from the top of the stile to its bottom, and the extender 25 is of substantially the same length as the stile and fits into this channel.

The space between the wing I5 and the front wall 33 of each stile-i. e., the space bounded by the portions 3 I, 32, and 33 of the lower portion of the stile--forms a channel 38 in which the lower sash is vertically movable.

Fig. 2 illustrates how the pane in the lower sash B rests on its bottom rail. This rail is an extruded element and comprises, in addition to the channel 40 in which the lower sash rests, a lip M which forms a handle for vertical movement of the lower sash, a groove 42 in the underside of the rail between the lip 4| and the channel 40 (the purpose of which will be explained immediately), and 2. depending lip 43 on the outside of the window. The lip 43 is close over the outside of the joint between the lower sash and the bottom panel 4 of the frame and helps to keep the rain and wind, etc, from penetrating the joint. The

vided to press the upper sash against the outer wall SI of the top and prevent rattling. By making the top wider than the stiles, by the width of the inner wall 62 of the top, and by cutting away unwanted portions of the top, and making the inside wall 62 somewhat longer than the other portions, the ends of the wall 52 fit against the inner face of the stile and are held in place by rivets 69.

The upper rail 10 of the lower sash and the bottom rail II of the upper sash (sometimes called meeting rails) are of extruded material. The outer wall 12 of the rail I0 and the inner wall 13 of the rail II are both beveled upwardly outward. As the two rails come together, the two sashes are spread: the upper sash is pressed against the element 20 and the bottom sash against the wall 33 of the channel 38. As a result there is a tight union between the two rails which prevents any rattlin of the sashes and keeps out the weather. The rail II rests on the stops I5 (Fig. 5).

As indicated, the top and two sides of the upper pane and the two sides of the lower pane are embraced by thin metal channels I5 for protection. These channels may be extruded but are preferably bent from sheet material and simply 7 clipped or sprung in place.

To assemble the window, the sash 5 is first put in place. The upper end of this sash is slipped into the opening 65 in the top I behind the springs 61 and is brought to rest on the stop I5. There is a little play between the top of the sash 6 and the stop 64 (Fig. 2) which permits lifting the sash a little above the stop I5 in bringing it to rest in that position. The lower sash 6' is then slid in place in the channels 38 behind the front walls 33 of the lower portions of the stiles. Figs.

channel 40 is made up of the outside and inside i walls 44 and 45 and the bottom 46. This channel 40 is lined with felt or the like to receive the bottom of the lower pane of glass. The ends 46 of this bottom rail advantageously extend into the channels 38 on opposite sides of the stiles. To form the projecting ends 46 of the channel, it is necessary to remove the ends of the lip III and the depending portion 43 and narrow the bottom portion 46 to a width not substantially greater than the width of the channel 40. The ends 45 should fit into the channels 38 with sufficient play to permit unhindered vertical movement of the lower sash.

is cut away a little below the middle rails down to the edges TI to permit tilting of the upper portion of the lower sash 6 inward as the sash is lowered in place, and when it is removed. As the sash is lowered, it is brought into the upright position; and as it comes to rest on the bottom panel 4, the wall 12 of the middle rail I0 of the lower sash slides against the wall I3 of the middle rail II of the upper sash so that the upper 3 sash is pushed outwardly against the inwardly The opposite edges of the panel 4 fit into the 7 channels 38 on opposite sides of the frame. To accomplish this, the ends of the tongue 50 which extends up into the groove 42 to form a weatherproof seal, must be removed. This bottom panel 4,as shown, is channel shaped and accommodates the narrow extender 53. The whole, or at least the upper portion of the extender 53 is corrugated, as indicated, so that it remains indefinitely at any adjustment. The panel 4 is riveted in place in the channels 38 by rivets 54 (Fig. 1), and the adjuster fits within these rivets.

The top I of the frame is composed of the top portion 60, the outside wall BI, the inside wall 62, the bottom wall 53, and the stop 64. This provides an opening for the top of the upper sash 5. The edges of the opening 65 are advantageouslybeveled, as indicated. Clips 61 are proprotruding portion 20 of the upper portion of each stile, and the lower sash is pushed inwardly against the front wall of the-channel 38. The beveled surfaces may be stepped in a complementary manner to form a tighter seal, if desired.

Instead of forming the stiles of the frame of two parts welded at the middle, they may be formed of two parts which are fitted together with a tongue and groove. This is illustrated in Fig. 7. Each stile is formed from top to bottom of the h-shaped extruded element I83 which contains the groove I04 which, likewise, runs from the top to the bottom of the stile. The element I05, which is provided with a tongue I06 which fits into the groove I04, is only the height of the lower sash and is slid into place in the lower part of the groove I04. Preferably, there is a notch I01 in the back wall of the stile to receive the backwardly projecting arm I08 of the element I05. When this type of construction is used, the upper sash rests on the arm I08 and the adjoining wall I09. The top portion of the front wall IIO of the element I05 is cut away, just as in the form of the invention just described the front wall is cut away to the edge 11 (Figs. land-5).

The extenders are advantageously spring pressed by springspreferably' located inthe channels. at the top of the-frame and at opposite ends of the "bottom panel" 4. Figs. :6-8 illustrate how these springs III may. be'fastened in'the channels. The overhanging lip H2 and vertical lip I I3 are extruded into the bottom of the channel and extend the whole length of the channel. There are two notches H4 in one side of the leaf spring III which permit it tobe slipped around the lip I I2. ..After the spring has been thus fitted over this lip, the other lip H3 is bent down at H5 over the portion of the'spring which lies in thebottom of thechannel-under the lip" II2. Fig. '7' show' the relation of the parts before the lip -I I3 is bent, and "Fig; 8 shows how a portionof thelip H3 is bent over-tohold the-spring in place. Other-meansforholding the spring in placemay be -used.

' Fig. 9-shows an alternative type-of spring'assembly. The view shown-in-Fig. 9 is similar to the view shown in Fig. 4 except that it is a cross section through the stile-instead of showing the top of the stile and a part of the top rail. The outer rest 220 for the lower sash 206 corresponds with the element 20 of Fig. 4. The cross element is identified by the-reference numeral HI and the inner element by the reference numeral 222. These elements correspond to the elements 2| and 22 of Fig. 4. The extender 225 need not have its ends corrugated. corrugation is desirable where there is no spring ,(Fig. 3) and may be used with a spring (Fig. 7) but is not necessary.

In the bottom of the channel shown in Fig. 9 two lips 2I3 are extruded. The spring 2I I which may be the same shape as the spring III (Fig. 6) is placed between these two lips and then with any suitable element the lips are bent over onto the spring as indicated in dotted lines. This holds the spring in place. The spring keeps the extender 225 extended against the wall of the openin in which the window is placed.

In fitting the window into place, the size of the opening for the frame is approximated. Exact measurement is not necessary, and it is not necessary to measure the angles at the various corners of the opening. oftentimes the angles vary from 90 degrees. With the storm window of this invention any small variation in the angles, due to sagging of the house, etc., is taken care of by the extenders. The measurements will ordinarily be sent to an assembly plant located in the general neighborhood of the installation. If preferred, the various parts may be cut to size at the factory and shipped to the assembly plant after the fashioning is completed. The stiles will be cut to length but will generally be made an inch or two longer than it is considered will be required. The top and bottom panel of the frame are then cut to length; the portions of the top which must necessarily be removed and the end portions of the bottompanel which must be removed are then preferably sawed away. They may be removed by abrasion or other means if desired. The middle rails of the sashes which may both be cut from the same piece are then cut to length. They extend from one stile to the other. The bottom rail of the sash is cut to the required length. If the ends 46 are to be narrowed to fit in the channels 38, the bottom and middle rails may be about the same length.

The panes are cut to size. The channels "I5 are cut to length and snapped over the sashes.

The middle rails 10 and 'II are placed over the panes of the lower 'and'uppier sashes and are'held in place by suitable packing. The :lower sash .is fitted into the channel of the bottom'rail withfelt or other packing to :hold it in place.- The front walls of the'channels tll of each stile are cut away to the edges TI to aid in the insertion and removal of the'lower sash. Thetop: rail I and'bottom panel 4 are then riveted in place in the stiles.

The window is now taken =from:the"assembly plant to the place of installation. The exact measurement from the-top to the bottom on each side-of the openingis made, anclzthestiles are cut tolength. One stile maybe somewhat longer than the other; The frame is then :put place,

and the side extenders '25'andthe bottom extender-53. are pulled out '(or. sprung out) to meet .the edges and bottom of "the opening; The extenders need notstick out uniformly along. the edges .of the'frame but only to the extent required to make a. tight fit with the edges of the opening. The window will then be secured in place as by nails. Nails having. a head-located on one -side of the shank 'mayrbeusedand driven into the window frame alongside the extenders with their heads bearing down on the extenders. Where desired, calking may be inserted between the extenders or the top of the frame and the walls of the opening. In this manner a substantially airtight and weather-tight seal is made around the stormwindow frame. The upper sash is then put in place and then the lower sash. The window is then completed and ready for use. In the summertime the sashes may be removed, and if desired, screens may be inserted.

Felt for insulation and for muiiiing the noise may be applied to various surfaces, as desired. For instance, the rest 20 for the upper frame may be covered with felt, and felt may be used in the channel 38.

Fig. 1 shows a type of ventilator I20 which may be used with the window of this invention. It is formed of a rod I2I fastened at both ends to the stile 2. Leaves I22 are supported on the rod I2I in such a way that they may be swun horizontally to one side of the rod or the other, to provide a rest for the sash at any desired level. When a selected leaf is swung toward the open window, and the window is then lowered, the lip 4I rests on the leaf. The ventilator may be of any desired length and formed with any desired number of leaves.

The invention is not limited to the exact arrangement and details disclosed and described. Neither is it limited to a structure which includes all the novel features described. It is defined in the appended claims.

This application is a continuation in part of my applications Serial No. 594,296, filed May 1'7, 1945, and Serial No. 629,547, filed November 19, 1945.

What I claim is:

1. A storm window with extruded stiles each of which has in its outer face a channel with at least one lip extruded in the bottom thereof, an extender movable in and out of the channel, and a leaf spring shaped. and positioned to press against the extender, one side of the central portion of the spring being against the base of the lip with a portion of the lip bent thereover.

2. A metal storm window frame each stile of which has a channel in that surface which is adapted to face one side of the opening in which the frame is to be located, and extending in a straight line longitudinally of the bottom of the 7 channel and uniformly spaced from both walls thereof a lip adapted to be bent over at any location throughout the length thereof at which the central portion of a leaf spring is placed with the ends of the spring spaced from the bottom of the channel.

3. An extruded stile for a storm window frame which has a channel in that surface thereof which is adapted to face the side of the opening in which the frame is to be located, and extending lengthwise throughout the bottom of the channel and uniformly spaced from the walls thereof a lip which is adapted to be bent over at any place between the ends thereof to hold the central portion of a leaf spring with the ends of the spring spaced from the bottom of the channel.

4. The method of assembling a storm window frame formed with a stile having a channel in that surface thereof which is adapted to face one side of the opening in which the window is to be located, with a lip extending lengthwise through the bottom of the channel and uniformly spaced from the walls thereof, which method comprises placing one edge of the central portion of a leaf iii spring against the base of the lip intermediate the ends of the lip with the ends of the spring spaced from the bottom of the channel, and then bending the lip thereover to hold the spring in position in the channel.
